Thanks Lal for your explanation.
In an earlier post, I wrote: I think both avijja and tanha also create or give rise to rupa below the suddhastaska level, i.e. sankhara, vinnana, vedana, etc.
I now think this is a mistake. Vinnana, vedana and sanna are not rupa. Vedana, phassa and sanna are cetasika, while vinnana is the overall experience of the cittas and cetasikas we experience in any given moment. See ‘Vinnana, Thoughts, and the Subconscious’
I apologize for any confusion arising from this mistake.
